Permeable sintered metal materials — Determination of fluid permeability 可渗透烧结金属材料——流体渗透率的测定
发布日期: 1987-09-24
第二版取消并取代第一版(即ISO 4022:1977)。在流体渗透性可用粘性和惯性渗透系数表示的条件下进行试验(见附录A)。不适用于直径很小的很长空心圆柱形试样。附录B给出了试验液体。
This second edition cancels and replaces the first edition (i. e. ISO 4022:1977). The test is carried out under such conditions that the fluid permeability can be expressed in terms of viscous and inertia permeability coefficients (see annex A). Does not apply to very long hollow cylindrical test pieces of small diameter. Annex B gives test fluids.
